Been up in this area a lot recently and been watching the river transition from winter to summer. Cache is placed near this guardrail protecting the water from cars. As long as you have the most basic Geocaching TOTT along with you the retrevial of this cache shouldn't be to bad. If you have nothing retrevial might be more difficult. I expect the ink to make it on the log for the smiley 
PLEASE REPLACE THE CACHE AS FOUND!!!
